Bodybuilders Anna Koo (L) and Fung Yin-ka (C) loosen up with bodyfitness competitor So Sin-ying, all of Hong Kong, prior to their event at the Hong Kong bodybuilding championships on June 14, 2009. The event included men's and women's bodybuilding championships and a bodyfitness event.

Do fitness competitors in the USA wear as much, or the same, color as the bodybuilders?

Maybe not quite as much, but still quite a bit. Maybe like 1-2 coats lighter. BBs tend to be a little darker, but So looks like she's skipping it completely! She'll look white as a ghost under the stage lights! Nobody of any race looks good without some color on stage. Actually, the girl behind her looks like she has no color on either, so it must be a Hong Kong thing.
